FISPENSING MACHINE FOR BOTTLED Application filed August 28, 1925. Serial No. 53,172.

This invention relates to a dispensing machine of the coin-controlled type and, While the invention is capable of application for dispensing different kinds of articles. it is 5 particularly designed to dispense cylindrical articles such as the cardboard Containers used for containing milk and other l'iquids.'

It is an object of this invention to provide a device of simple andetlicient construction 10 adapted to contain a large number of articles or receptacles which may be singly dispensed in a simple and easy manner.

It is a further object of the invention to provide such a device'compri-sing a closed casing having therein a rotatable means carrying a plurality of magazines in which the articles to be dispensed are contained, to-

, get-her with means for moving said carrierv and projecting and delivering one of the articles or receptacles. 7

It is another object of the invention to provide such a device comprising a. rotatable table which carries a plurality of circumferentially spaced cylindrical magazines in which the t It is still another object of the invention to provide a simple novel and eflicient means for ejecting the articles dispensed, for locking the table above mentioned in fixed, position, and for rotating said table, step by step.

These and other objects and advantages of the invention will be fully set forth in the following description made in connect-mu with the accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in which 1 1s a view in elevation of the dewce; Fig. 2 is a vertical. section taken on the line 2-2 of Fig. 1, as indicated by the arrows;

Fig. 7 is a vertical section taken on the line 7-7 of Fig. 6,. as indicated by the arrows; and i Fig. 8 is a vertical section taken on the line 88 of Fig. 6, as indicated by the arrows.

Referring to the drawings, the device'com-- prises a cabinet or ca. ing, 15. lVhile this cabinet may be of various forms, in the embodiment of the invention illustrated, the same is shown as rectangular in horizontal cross section and having a flat top and bottom. Said cabinetpreferably is constructed of spaced.

walls 15 between which is disposed suitable heat insulating material 15 The. casing or cabinet 15 is also shown as provided with short legs 16 at itsb'ottomby which it is supported upon a-suitable surface. The casing 15 is provided with a door to give access to the interior thereof for replenishing the magazines therein a-ndfwhile this door may be variously located and constructed, in the em bcdiment of the invention illustrated, the same is shown as in the form of a lid 15? having spaced handles 17 thereon. A partition 18 extends across casing'15 spaced some distance from the bottom thereof, which partition is substantially horizontal but has an oliset portion18 to accommodate certain opcrating parts in the casing. The chamber below partition 18 is adapted to form a refrigerating chamber and the same may contain some refrigerating apparatus or medium, such as the ice cake shown as B. The casing 15 is provided'at one side with a door 19 open ing into the chamber below partition 18,

whichdoor will be suitably hinged and pro vlded with a suitable locking mechanlsm. A

platform or plate 19 is also supported in casing 15 upon an angle bar 20 extending across one side of semi casing and by spaced bars 21 also extending acrosssaid casing.

A hearing block 22 is disposed on the partition 18 and a bearing block 23 is also supported above block 22 on the platform 19. The bearing block 22 supports an antifriction bearing 2 1, the upper member of which'is secured .to a shaft 25 journaled in the blocks 22 and 23 and in platform 19. An upper anti-friction bearing 24 also surrounds shaft 25, the upper member of which is secured to a rotatable table 26, and the lower I member of Which is supported by the hub of an arm 54: to be later described. The shaft 2 1 has secured thereto a beveled gear 27 adapted to mesh with a similar beveled gear 28 secured to a shaft 29 journaled in the bars 21, and also in a bearing block 32 disposed in the wall of the casing 15. The shaft 21 also has secured thereto a disk 30 which is shown as vertically disposed, and the lower end of whicl'i extends into the chamber or bracket formed by the offset portions 18 of partition 18. The shaft 29 also carries, outward of the disk 30, a gear 31. The gear 31 meshes with a smaller gear or pinion 33 secured to a shaft 3% also journaled in block 32 at one side of shaft 29 and the shaft 34 projects outward of the casing 15 and has a crank handle 35 secured thereto. A pawl pivoted to a small block on the inner wall of casing 15 co-operates with the gear 31- so that shaft 34 can be turned only in a clockwise direction by the crank 35. The disk 30 has secured thereto at some distance from its center, a weight member 87 and said disk is provided on its edge with a notch 30 and is further provided with an opening 30 illustrated as of rectangular form for a purpose to be later described. 7

The notch 80 is adapted to be engaged by the toothed end of a slide member 38 guided in a bracket 40 secured to the inner wall of casing 15, which slide'moves through a downwardly inclined narrow coin chute 41 which extends diagonally downward toward slide 38, said chute extending through the wall of casing 15 at its upper end and provided with an open horizontally disposed end outward of said casing. The slide 30 has a slot 38 therethrough, the upper surface of which is convexly curved to form a cam surface. Said chute below and at the inner side of the slide 38 extcnes into a coin receptacle 42. The chute has an intermediate downwardly curved portion 4.1 having a slot in its lower side through which is adapted to project a horizontal side 13 guided in a portion 40 of bracket 40. The slide 43 is normally held in a retracted position by a tension coiled spring ia; secured to its outer end and to one side of casing 15. Said slide 13 is adapted to be moved, however, by a handle 4-5 projecting laterally from one side thereof and extending through horizontal slot 15 in the wall of casing 15. As shown in Fig. 3, the bracket 40 is also constructed to form the bottom of the chute 41 adjacent slide 48. The table 26 supports a multiplicity of vertically disposed cylindrical magazines 16 and it will be noted that these magazines, as shown in Figs. 2 and 5, project over the edge of said table, said magazines having their lower portions cut away as indicated at 46, and also have openings 46 at their inner radial sides which openings are illustrated as of rectangular shape. Each of the magazines 4:6 is adapted to receive a plurality of superposed c 'lindrical articles ll such as cardi l board containers for milk. The table 26 is adapted to be locked in fixed position, and for this purpose the same carries on its lower surfaces a plurality of circumferentially spaced blocks 18, each having a central slot 48 therein. extending radially of the table 26. A sliding bar &9 is mounted in brackets 50 upstanding from platform 19 and has an upwardly extending projection or tooth 1-9 at its outer end adapted to enter the notches 18 The bar 49 has a pin 51 extending transversely therethrough and projecting at its sides against which presses one end of a compression coiled spring 52, the other end of said spring contacting the side of one of the brackets 50. Spring 52, therefore, normally tends to move bar 41-9 and bring tooth 49 into one of the slots 48 The inner end of bar 19 is adapted. to be contacted by a cam member 58 "having. an.

outer curved cam face, which member 53 projects from an arm 54 having a hub keyed to the shaft 25. Arm 54 also carriesa'n. outer hub in. which is vertically slidable a pin 55.

The pin 55 is adapted to be raised at intervals by a cam projection 19 mounted on platform 19. The table 26 is provided with a series of circumferentially spaced holes 26 said table being cut away at the lower side of said holes to form slots 26 having inclined upper surfaces, as shown in Fig. 8.

The upper end of shaft 25, above table26, has secured thereto an arm 56, above which and at the outer end of which is pivoted a link 57, the other end of said link being pivotally connected to and beneath a plunger 58 spaced some distance therefrom. The plunger 58 is mounted for sliding movement in a depending portion 59 of a bracket 59 extending across the bottom of lid 15 and having downwardly extending portions. at its side secured to the inner wallsof casing 15, the portion 59 being illustrated as having spaced sides for the greater portionof its length. The plunger 08 is provided with a head 58 having a concave forward portion and it will be noted that the central longitudinal axis of plunger 58 is radial with table 26 and that said concave portion of'plunger head 58 is'concentric-with the center of one of the magazines 46 when in the position shown in Fig. i.

A chute 60 is )rovided havin substan &

when the parts are in the posit-ion shown in Figs. 2, 3 and l. The outer portion 60 of said chute'extends to and alines with an opening 15, in the side of casing 15, which on e of which extends in close proximity to tion.

erating engagement with the edge of disk 30.

.111 operation, the lid 15 will be removed and the magazine 46 will be filled with the articles or receptacles 47. It will be understood that the lid 15 normally will be securely locked in closed position. The parts normally will occupy the position shown in the drawings in Figs. 1 to 4. Q When it is'desired to secure one of the articles 47, such as a carton of milk, the operator will insert a coin of the proper dimension which designation will be indicated by aninscription on the apparatus, into the chute 41. The coin will roll down said chute and take the position indicated by coin 67 in Fig. 3; The op erator now takes hold of handle 45 and moves the same to the right, as shown in Fig. 1, in the slot This moves horizontal slide 43 against the tension of spring 44 and this slide pushes coin 67 into the opening 38 of verti cal slide 38. The coin engages the cam surface at the top of opening 38 and slide 38 is cammed upwardly so that the tooth at the When lower end is moved out of slot this occurs, the weight 37 which normally is in the position shown in Fig. 3, moves downwardly revolvingdisk 30 so thatwhen the handle is released the slide 38- cannot again enter notch 30 The operator, after' passing the handle 45 to the right releases thesame and then rotates crank handle 35. Upon releasing of handle 45 spring 44 retracts the same and slide 43 to normal posi- Crank handle '35, as stated, must be rotated in a clockwise direction. .Rotation of crank handle 35 rotates gears 33 and 31,

shaft 29, and through gears 27 and 28, shaft 25. Arm 54 is thus turned and the cam 53 moved against the inner end of plunger slide 49 moving tooth 49 out of the slot 48 in which it has been engaged. As arm 54 is thus rotated, pin 55 moves upwardly on cam 19 When tooth 49 is moved out of slot 48, pin 55 encounters the end of vertical wallof the slot 26" and one of the holes 26 and begins torotate table 26 which rotates on the upper anti-friction bearing 24. a The rotation of table 26 continues until pin 55 moves off of cam 19, when said pin drops out of the slot 26" and ceases to operate said table. At this time the next notch 48 will be brought into alinement with tooth 49 and spring 52 again moves tooth 49 into said slot. The shaft 25 makes a complete rotation and, during this rotation arm 56, through its link 57, moves forward the plunger 58. This plunger58 movesoutwardly 1ts head 58, engages one of the articles or receptacles 47 in one of the magazines 46, and as said magazine isin alinement with chute 60,"sai'd plunger reaches its outmost position. The article orreceptacle 47 is thus pushed off of. table 26and slides down into chute 60, against disk 30. When opening 30- becomes alined with said chute.

upon further rotation of disk 30, said article will pass into the outer portion 60 of said chute. The operator can now lift door 61.

I and remove the article 47, it being noted that crank 35 is out of alinement with said door at this time. As the disk 30 is rotated, the slide 38 will again engage notch 30 and further rotation of crank 35 in said disk is prevented until'another coin is placed in the machine. The rotation of the disk 30 operates the counter 66 which is suitably adjusted to correctly count the numberof operations. Asst-ated, the interior of casing 15 is kept at a low temperature bythe refrigerating medium, such'as the ice B which canbe placed therein through the door 19.

From the above description it is seenthat applicant has provided an extremelyv simple andefficient dispensingmeans and onewhich has ahigh degree of utility for'storing and dispensing milk or other liquids in cartons. The machineis quite simple in construction and requires few manipulations by the operator. j The machine is such that it can be easily transported andplaced at the'desir'ed locations.- The machine can be located, in factories, office buildings, and similar establishments so that a large numberof' people can easily andquickly secure a bottle of milk or other liquid therefrom. The milk or liquid will be contained in cardboard or paper receptacles which may be discarded after use. It will thus'not be necessary to have an 'attendant at the machine and the owner of the machine will only have to replenish the same at intervals and collect the moneywhich is being deposited in the coin receptacle' 42. The machine, of course, will have "thereon an inscription on a plate, or otherwise, directing the operator how to manipulate the handle-45 and crank 55 after placing a coin in chute 41; a i 1 It will, of course, be understood, that various changes may be made in the form, details, arrangement and proportions of the parts'without departing from the scope of applicants invention, which, generally stated, consists in a, device capahle of carrying out the objects above set forth, in the novel parts and combinations of parts disclosed. and defined in the appended claims.
